COMBINED RAKE All!) TEDDER."

Specification of Letters Patent. Patented Fgly 21 1922.

Application filed March 12, 1920. Serial No. 365,166.

To all whom it may concern.

Be it known that I, Bonner R. Bowers. a citizen of the United States, and a resident of Ottumwa, in the county of \Vapello and State of Iowa, have invented-certain new and useful Improvements in Combined Rakes and Tedders, of which the following.

is a specification, reference being had to the accompanying drawings.

This invention relates to that type. of sidedelivery rotary rakes wherein is journaled in a suitable diagonally-arranged frame a rotary reel that is provided with a plurality of rows of raking teeth all of which are maintained at substantially' the same angle so as to be presented alike to-the hay on the ground. Said several rows of teeth are held in, the desired working position by means of suitable mechanism that is carried by the forward or inner reelhead, such mechanism ordinarily comprising a set of gears in connection with the bar to which each row of rake-teeth is connected and a single other gear that is disposed centrally of the several sets and. is in constant mesh with the inner gear of each of saidsets.

It is the leading object of this invention to provide improved means for readily and easily changing the direction of rotation of the said reelso that the nachine'may be alternatively employed as a rake to gather the hay into windrows or as to tedder to scatter it for drying. Another object is to so construct the machine that in addition to the ordinary vertical adjustment that, is

provided for the outer or rear end of the reel by a bodily movement of its frame with respect to the usual supporting casterwheel or wheels an independent vertical movement for adjusting purposes can be given to thereel itself when the machine is in use either as a rake-or as a tedder. These objects I attain by theconstruction andarrangements of parts shown in the drawings and hereinafter particularly pointed out. That which I believe to be new will be set forth in the claims.

In the drawings,--

Fig. 1 is a plan View of a machine c111 bodying my improvements;

Fig. 2 is a detail, being an enlarged plan view of a portion of the front end of the machine and illustrating the meansfor rotating the reel in either direction;

Fig. 7 is a view similar to Fig. 6 but with the parts in position to compel the machine to operate as a tedder;

Fig. 8 is a plan view of the clutch-shifting lever and certain parts connectedtherewith; and

Fig. 9 is a cross-section through the axle of the, machine, such section being taken at line 9-9 of Fig. 5; and r I Figs. 10 and 11 are views similar to Fig. 4, but on a smaller scale, and respectively showing the position of the parts when the forward end of the reel-shaft is adjusted to its lowest and highest positions.

Referring to the several figures of the drawings, LO-10 indicate a pair of carrying wheels mounted upon an axle 11 and such axle will be so connected with the wheels 7 as to be rotated during the forward movement of the machine but not rotated when the machine is backed. Such connecting means between an axle and a wheel are well understood in the art and, therefore, I have not deemed it necessary to here illustrate the same. 12 indicates an ordinary diagonally-disposed reel frame which is connected with the axle 11 so as to rock freely thereon when the frame is adjusted relatively to its usual rear ground-engaging support or supports. Two short sleeves 13 and 1e, loose upon the axle 11, form. hearings to which projecting portions of the frame 12 are attached for connecting the reel-frame with the axle. 15 indicates the usual long bar, that extends from the axle 11 back over the reel-frame, to which frame it is connected near its rear end, the forward end of the bar being secured as usual to a sleeve 15 on the axle and thus constituting another rocking connection of the reel-frame to the axle. 16 indicates a bent supplemental frame section that is rigidly connected with and forms an extension of the reel-frame 12, said supplemental frame extending forward of the axle and furnishing means for the attachment of the usual draft devices. As shown, the machine is provided in the rear with two caster wheels 17 which serve to support the rear end of the reel-frame, and the reel-frame is adjustable vertically with reference to those caster wheels in any usual way. As shown, such adjustment is effected through the movement of the connected link and chain members 18 that are operated by an ordinary hand lever pivotally mounted on the truss bar 15 within convenient reach of the drivers seat,certain of the chain members shown passing over pulleys supported in brackets adjacent to the standards of the caster wheels and connected with such standards. As such adjustment of the rear end of the reel-frame is common and well-known and may be accomplished by any wellknown devices, I do not deem it necessary to'here describe them any more in detail.

The reel that is rotatably mounted in the frame 12 comprises two heads connected together by a plurality of bars, to which bars the rake-teeth are connected in the usual manner. The inner or forward one of these reel-heads is indicated by 19 and the outer or rear reel-head is indicated by 20. The tooth bars above mentioned are indicated by 21 and, as is usually the case, three such bars will be employed. 22 indicates curved guards that are secured to the front and rear members of the reel-frame, their function being to strip from the reel teeth any hay that might tend to be carried around by the teeth.

While I have not shown any mechanism for controlling the positions of the tooth bars 21 so as to maintain the several sets of teeth that are carried by these bars in proper position, it is to be understood that, as usual, the inner or forward reel-head 19 will be provided with such mechanism, which mechanism will preferably consist of a plurality of sets of gears rotatably secured on the outer face of such head, one set being provided for each tooth bar and the outer gear of each set being keyed or otherwise secured to the forward end of one of the tooth bars as usual. Furthermore, upon the reel-shaft will be mounted a smaller gear which is normally held against rotation and with which one member of each of the several sets of gears before mentioned will be in constant mesh. I have not illustrated the arrangement of such gearing, a it forms no part of my present invention and is an arrangement well understood by those acquainted with this art. It is, however, very fully shown and described in Letters Patent, No. 886,681, dated May 5, 1908, granted to Joseph Dain, and while in said Dain patent such central gear is at all times held against independent rotation, I prefer to provide for a slight turning of such central gear in order to be able to vary the inclination of the several sets of rake-teeth and I, therefore, prefer to mount such central gear rotatablyandcontrol the amount of its rotation by means of an adjusting lever 23 that interlocks with a pivoted sector 24, which latter construction is very fully set forth in Letters Patent, No. 1,283,674, dated October granted upon the application of one Leon R. Clausen. The central shaft, hereinbefore referred to, upon which the rotatable reelframe is secured, is indicated by 25. This reel-shaft is preferably angular in crosssection, as shown, (see Fig. 4) and as its inner or forward end is capable of being adjusted up and down as hereinafter described, the bearing, indicated by 26, for

the other end of the shaft must, of course,

be large enough not to offer any obstruction to such adjustment. In other words,

that outer end bearing must-be so shaped as to permit a limited rising and falling movement of the shaft when the inner end of the shaft is vertically adjusted. Such inner or forward end of the reel-shaft is supported (see Fig. 4) in a bearing 27 that lies within an elongated opening 28 in a bracket 29 that depends from and is bolted to the inner or forward end member of the reel-frame 12. Formed with this bearing 27 in the construction shown, is an upwardlysextending arm 30 to which is bolted a hand lever 31 thatis adjustably connected by the usual spring latch with a curved and notched rack 32 bolted to and rising from said end member of the, reel-frame. The rear curved edge of the elongated opening 28 is toothed to provide a short rack and a portion of the circumferenceof the bearing 27 is provided with teeth that mesh with that rack, and it will be evident that by a movement of the lever 31 the bearing 27 can be'adjusted up or down, with a consequent movement of the forward end of the reel-shaft, and the desired adjustment will be maintanied b the interlocking of the lever 31 with its curved rack32. The

width of the opening 28 is such that the bearing 27 therein cannot have its teeth disengaged from the short curved rack in the edge of the bracket.

Turning now to the means by which the mesh with the bevel gear 33.

a clutch member 34. 35 indicates an internal bevel gear also loosely mounted on the axle 11 and located a short distance from the bevel gear 33,-this internal gear 35 also having an end portion of its extended hub spaced apart by the short sleeve portion of the bearing 13. against the ends of which the elongated hubs of the two gears abut. 37 indicates a clutch member slidably but non rotatably mounted upon a short sleeve 37 on the axle 11, the non-rotation being accomplishcd, in the construction shown by ribs 37 formed on said sleeve, which ribs project into grooves in the inner face of the clutch member 37 (see Fig. 9). The sleeve 37 a is held connected to the axle by a key 38. The clutch member 37 is adapted to be moved into and out of clutching engagement with the clutch member 34 so as to, at the will of the driver, connect the bevel gear 33 to or disconnect it from the axle 11. A similar sliding clutch member 39 is provided for cooperation with the clutch member 36 so as to connect the internal bevel gear 35 to or disconnect it from said axle. This clutch member 39 is slidably mounted upon a sleeve 40 that is keyed tothe axle, and at its outer end such sleeve carries a short laterally-projecting arm 41 that, as shown, has a tooth or lug onits outer face which in intended for engagement with ratchet teeth in a drum 42 (shown in Fig. 1) carried by the adjacent wheel 10. As such construction is a common one I have not deemed it necessary to illustrate the said ratchet and the actual engagement of the arm therewith.

43 indicates a short shaft extending diagonally rearward from the axle 11 with its axis substantially parallel with the axis of the reel-shaft 25. This short shaft 43 issupported at its forwardend in a bearing 46.

which is shown (see Fig. 3). integral with the sleeve member 13 and at its rear end, it is supported in a bearing 47 carried by the depending bracket 29. Rotatably mounted upon this short shaft 43 is a bevel gear 48 that is in constant mesh with the internal bevel gear 35 and also upon such shaft is another bevel gear 49 which is in constant As shown in Fig. 3,these two bevel gears 48 and 49 that are in axial alinement are connected together by a sleeve portion 50. Formed with the gear 49 and in rear of such gear is a comparatively large internal gear 51 which lies but a short distance from and substantially parallel with the forward or inner end member of the reel-frame 12. gear 51 is so disposed as to permit the projection thereinto of the forward end of the This internal reel-shaft 25 and upon such forward end of that shaft is secured a pinion 52 which is in constant mesh with the teeth of the internal gear 51, and it is by reason of such engagement that the reel-shaft and reel are rotated in either direction as hereinafter described.

In order to adapt the machine for use as an ordinary side-delivery rake, the sliding,

clutch member 37 is to be moved into engagement with the clutch member carried by the bevel gear 33, while to adapt the machine for use as a tedder the clutch member 39 is brought into engagement with the clutch member 36 carried by the internal gear 35, and the means that are employed for effect ing either of these clutching engagements are as follows: a longitudinally-movable bar 53 (see Fig. 5) is supported over the axle 11 in bearings 54 and 55, which bearings are suitably supported from the axle 11 and the framework of the machine. The bar 53 is bent as shown in order to pass over the gear members 33 and 35 on the axle. Secured to the bar in the proper position to suitably engage the movable clutch members 37 and 39 are yokes 56 and 57 respectively and on the end portion of the bar that projects beyond the'yoke 57 is a coiled spring 58 that bears at one end against the yoke 57 and at its other end against a pin passing through the bar. Between the yoke 56 and the end of the bearing is another coiled spring, in dicated by 59. To theinner end of the longitudinally-movable bar 53 is pivotally'con nected a hand lever 60, the attachment of the hand lever to the bar being by means of a heavy pin 61 upon which pin is also j0urnaled a block 62.

This block, as best shown in Fig. 8, is a structure that comprises two side walls spaced apart and connected at their outer ends by an end wall, and it is sodisposed that the two side walls referred to lie on opposite sides of the inner end portion of the bar 53-the lever lying alongside one of the side walls of the bar. To the side wall last referred to is rigidly secured a notched segment 63 having, in the construction shown, two notches therein, indicated respectively by 64 and 65, with either of which the spring-pressed latch of the lever 60 is adapted to engage. By turning the block 62 by means of the lever 60 either of the movableclutch members 3739 can be caused to move into" clutching engagement with its cooperating member. For example, with the mechanism in the position represented by Fig. 5 where both of the clutch devices are shown in neutral or inoperative position, a downward stroke of the lever to the position shown in Fig. 6 will cause a turning of the block 62 so as to bring what was formerly its lower edge into position coiled springs 58 and 59 yielding sufficiently to permit the bar 53 to move endwise as the block turns to this position. Such turning of the block into the position shown in Fig. 6 will cause a clutching engagement of the clutch 37 with the gear 33 and the force of the spring 59 will hold the block 62 in its new position and insure the continuation of the clutching engagement last mentioned. If, however, instead of having the gear 33 clutched to the axle in the manner described, and which will cause the machine to act as a rake, it be desired to clutch the internal bevel gear 33 to the axle, the latch 01 the lever 60 is to be released from the notch 6%, as it is shown in Fig. 5. and the lever then turned down and its latch caused to engage the notch after which'an upward pull onthe lever will cause a turning of the block into the position shown in Fig. 7 whereby the bar 53 will be drawn lengthwise inward-that is, toward the driver on his seat-causing the sliding clutch member 39 to engage the clutch member of the internal bevel gear 85, and of course carrying the othersliding clutch member 37 to a distance from the clutch member of the bevel gear 33, as seen in Fig. 7. These endwise move ments of the bar and consequent shifting of the movable clutch members as described,

are permitted and compelled by reason of the location of the pivot pin 61 with respect to the block tlnrough which it passes. As shown, the location of this pivot pin is quite close to one of the bearing edges of the block and at a very considerable distance from the other bearing edges and such block may, tliereiormbe said to constitute an eccentric, and as such it will, when movingto one position, .force the bar longitudinally in one direction and when moving to another position draw the bar in the opposite direction. and when seated along any one of its three acting edges against the end of the bearing 55 will, under the influence of the coiled springs, firmly hold one only of such clutches in clutching engagement as described. To prevent any axial. turning of the bar 53 and the lever 60 and the block 62 connected therewith, I provide a projection 66 on the end of the bearing 55 of sufficient width to extend into the space between the side walls of the block 62- see Fig. 8. In whichever adjusted position that the block is turned to such projection will extend between the side walls thereof and effectually prevent any tendency of the bar 53 and-attached parts to rotate-tlms insuring the hand lever 60 always being in proper position for operation by the driver while on the seat.

The machine will be driven to and from a field where it is to be operated, with the clutch-adjusting mechanism in the neutral or inces /'0 inoperative relation shown in Fig. 5. \Vhen the machine is ready for use the lever (30 will be operated in the manner described to cause a clutching engagement with the axle 11 of either the bevel gear 33 or the internal bevel gear 35, depending upon whether the machine is to be used as a rake or as a tedder. If the bevel gear-33 is engaged by the sliding clutch member 37 the machine will operate as a rake due to the fact that the bevel gear 19 is rotated in the proper direction to effect a forward rotation of the reel-shaft 25 through the intermeshing of the gear 52 on its end with the internal gear 51 that, in the construction shown, is integral with the bevel gear e9. It will be evident also that a re verse rotation of the reel-shaft will be effected so as to cause the machine to act as a tedder, when the internal gear 35 is clutched to the axle 11, this reverse rotation being due, as will be readily understood, to the fact that the power is applied to the connected parts 48, 49, 50 and 51 at the same side of the axle as in the I other case but applied by means of an internal'gear. It will also be understood that by reason of thetwo gears 48 and 49 being connected together and such gears being in constant mesh with the gears 35 and 33 respectively, that that one of the gears 33-35 that is not in clutching engagement with the axle will, ofcourse, be rotated loosely on the axle when the machine is in operation either as a rake or as a tedder.

At any time during the operation of the machine, either as a rakeor as'a tedder, the driver can readily make the desired adjustments of the reel, one of such adjustments being by means of the lever that controls the connections to the caster-wheels 17 whereby thereel-frame as a whole can be vertically adjusted at its rear end with respect to such caster-wheels, and the other adjustment being of the reel alone, and which independent adjustment of the reel is performed by a stroke of the hand lever 31 which will cause a movement up or down ofthe bearing 27 in the elongated opening 28 of the bracket 29, which hearing, as stated,supports the inner end of the reelshaft. By reason of the character of the bearing for the outer or rear end of the shaft this last-named adjustment is permitted. In such independent adjustment of the reel-shaft, the inner or forward bearing 27 is moved in a slightly curved path which is the arc of a circle struck from the axis of the short diagonalshaft 43 and hence the pinion 52 on the reel-shaft is always maintained in proper engagement with the teeth of the internal gear 51, so that no matter in what position the forward or inner end of the reel-shaft may be adjusted to, the pinion 52 that it carries is always maintained in proper position to be .driven by the rotation of the said internal gear 51.
